I agree that you will find bias on either side of the argument. So what do we do about it? Is one side always right or always wrong? Of course not. Is there someone out there who has a genuine desire to deliver bias-free studies? Probably so. Will we trust them when they give us a study? Probably not. Like I said, I'm from the "abundance of caution" school. I'd much rather find out that I'm wrong, and that the fish are fine, and that we've unintentionally screwed a bunch of comms than to find out later that I'm right, long after the time when we could do something about it.
Oh yeah, I didn't say that there was anything wrong with your wacky swordfish tobacky... as a matter of fact... half the guys on this board could do with a toke or ten... I, however, will take the fifth on this one... Hell, I'll take the whole half-gallon...
